This research aims to find the information concerning nutritional status and food intake in Korean diabetic men. Thus, the survey was made on 202 NIDDM patients over 35 age at University Hospital. The data were analysed using F-test and mutiple comparison in SAS package program. Main results were as follows: Incidence of diabetes is high in their forties and fifties. Most of them are salary men, administrators, and proffesionals in middle class, who reside in metropolitan area including Seoul. They used to take light exercise and were founded NIDDM by subjective symptoms. 36.6% of them have other diseases simultaneously such as hypertension, cancer, etc. Food intake pattern prior to incidence was that intake frequency of grains, sugars, protein foods, and liking foods was higher than of proccesed foods. Amounts of calorie intake were shown to be lower than normal persons, so that it seemed to be controlled by doctors. In addition, the calorie ratio derived from fat was lower than RDA. Thus protein and carbohydrate ratio was relatively higher than RDA. Total mean fatty acid intake was 32.15g and it is no significance among weight groups in various fatty acid intakes. With respect to the physical standards of the diabetic men, weight, PIBW, BMI, BMM, TST, arm circumference, and waist/hip ratio were higher than in normal. Therefore it seemed that these factors would be related to the diabetics. From now on, it is reqiured to research the correlations of fatty acid intakes on the diabetes and their influence to serum lipid profiles.

To examin ripening in peach types, cell wall contents and Polygalacturonase activity were compared in Changbang, Daegubo and Yumyung peaches. Among peach types, the hardness of Daegubo was the lowest. Yumyung peach had the highest content of alcohol-insoluble substances and Changbang peach of cell wall. The contents of total and insoluble pectic substances were little different between Changbang and Yumyung peach, while the lowest in Daegubo. Daegubo peach had the highest activity of polygalacturonase, Changbang and Yumyung peach in succession.

Effects of metal chelating agents and metal ions on the volatile substance of cooked oil with chicken and pork mixture meat were examined by chemical analysis and sensory test. The addition of Na-tripolyphosphate(Na-TPP) to chicken and pork mixture meat increased the amount of H_2S among volatiles evolved during cooking but decreased that of volatile carbonyl compounds(VCC). This treatment enhanced meat flavor in cooked oil with chicken and pork mixture. It was recognized that the increase in H_2S evolution was caused by the rise of pH value. On the contrary cupric ion produced a negative effect on the production of chicken and pork mixture meat flavor and this addition increased VCC and TBA value. Other metal chelating agents such as citric acid, phytic acid and EDTA, provided the same results as Na-TPP. It was supposed that these phenomena were attributable to the chelating action to metal prooxidant in mixture meat. It could be concluded that a proper evolution of H_2S and protection against lipid oxidation during cooking were important to produce an excellent chichen and pork mixture meat flavor.

동물실험에서 실크단백질 산 가수분해물을 투여하고 t-BHP투여한 군의 혈액 생화학적 검사 결과t-BHP만 투여한 군과 비교하였을 때 AST, ALT 그리고 LDH가 실크단백질 산 가수분해물의 투여 농도가 높아질수록 수치가 감소하는 것으로 나타났고 세포가 손상할 시에 증가하는 MDA를 간 조직을 대상으로 측정한 결과 실크단백질 산 가수분해물의 농도가 높아질수록 수치가 대조군과 유사한 정도로 감소하는 것으로 보아 간 손상에 관여하는 효소의 누출 억제효과가 있는 것으로 사료된다. HPLC로 간 조직에서의 GSH측정결과t-BHP만 투여한 군과 비교하였을 때 유의적으로 증가하였고 조직학적 검사 결과 t-BHP만 투여한 군과 비교하였을 때 실크단백질 산 가수분해물을 투여한 군이 대조군과 가까운 모습을 보이는 것으로 관찰되어 실크단백질 산가수분해물이 산화적 스트레스로부터의 간 보호 효과가 있는 것으로 사료된다. 따라서 실크단백질 산 가수분해물의 기능적 소재로서의 이용가능성이 확대될 것으로 사료된다.

본 연구에서는 락툴로스(lactulose) 51.67%와 갈락토올리고당(galactooligo saccharides) 15.8%로 이루어진 듀올리고(DuOligo)의 섭취를 통하여 피부개선 효능을 조사하였다. 40 ∼ 60 대의 건강한 여성 37명 을 대상으로 대조군(덱스트린)과 실험군(듀올리고군)으로 나누어 각각 8주 동안 섭취 후, 수분보유량, 경표피수 분손실량, 멜라닌지수, 홍반지수와 주름지수를 측정하였다. 그 결과, 듀올리고 섭취 8주 후의 수분 보유량은 대 조군에 비하여 수분 보유량이 38.22% 유의적으로 증가하였다(p < 0.01). 대조군의 경피수분손실량은 8주후 3.39 g/h/m2로 감소한데 비하여 듀올리고군의 경피수분손실량은 8주후 5.32 g/h/m2 감소하였다. 대조군의 멜 라닌 지수는 시간에 따라 그 값이 유의적으로 증가하였으나, 듀올리고군의 멜라닌 지수는 시간에 따른 유의적 차이가 나타나지 않았다. 또한, 듀올리고군은 대조군에 비하여 주름의 총 넓이, 총 주름의 길이, 주름의 수 및 주름의 깊이가 확연하게 감소하였다(p < 0.05). 듀올리고의 피부개선 기능성 소재로서의 응용 가능성을 확인하 였다.

Although scrap domestic refrigerator is regarded as a major source of HFC-134a, little information is available for its emission characteristics of HFC-134a. This paper addresses the fugitive emission factors of domestic refrigerator at usephase and disposal-phase. The residual quantities of Korean-made forty three scrap domestic refrigerators were weighed using a commercial recover of refrigerants to determine the emission factors at the disposal-phase. On the other hand, the emission factors at use-phase were estimated from the residual quantities and operating times. The average residual rate of forty three scarp domestic refrigerators is determined to be 75.1 ± 5.2%. The emission factor at the use-phase is estimated to be 2.4 ± 0.5%/yr as a result of using average age of 12.3 years and the average residual rate determined here. The emission factor at the disposal-phase is determined to be 31.9% after adopting 38% of the recycling rate of refrigerant reported by Recycling Center. We estimate 2.9 g/yr for the average emission quantity of HFC-134a per operating refrigerator, while 33.5 g for that per scrap domestic refrigerator. Since the chemical compositions of refrigerant of scrap domestic refrigerator were the same as those of new refrigerant, it is expected that the HFC-134a recovered from scrap domestic refrigerator can be reused for refrigerant.

This paper attempted to estimate the emissions of HFC-134a from scrap passenger vehicles as a result of measuring the residual quantities of HFC-134a in scrap vehicles. We measured the residual amounts in the scrap passenger vehicles of 196 by applying commercial recover for refrigerants. The average residual rate is reported to be 61.2 ± 2.4% with a confidence interval of 95%. As expected, the higher residual rates are shown for recent models. Little variation, however, is made with vehicle size. The HFC-134a emission quantity from scrap passenger vehicles in 2011 is estimated to be 326,236.83 tCO2 eq that demonstrates 53% increase to compare with that in 2007. As the numbers of passenger vehicles have increased dramatically during the last two decades, the emissions of HFC-134a from scrap passenger vehicles would increase sharply in the next coming years. The chemical compositions of refrigerants from scrap passenger vehicles are quite similar to those of new refrigerants, suggesting that the refrigerants from scrap passenger vehicles could be reused.

코지와 대두의 혼합비율을 달리하여 제조한 된장을 60일간 숙성하면서 품질을 비교 평가하였다. 대두와 현미코지의 비율은 1.5:1 (BR-1), 2:1 (BR-2), 3:1 (BR-3)로 하고, 대조구로써 대두와 백미코지를 2:1 (PR)로 하였다. 60일 숙성 후 수분과 염도는 시료 간에 큰 차이가 없었으나, 숙성 경과에 따라 pH, 산도 및 미생물수는 숙성 20~30일 째에 최대에 이르렀고. 이에 앞서 10~20일째에 환원당 함량과 에칠 알코올
